Review analog pins numbering and pin functions
analogRead(A0) == analogRead(0) analogWrite(A0) != analogWrite(0) == analogWrite(D0) All pins available in PinMap_ADC are available with Ax alias Fix stm32duino#37 Move pin functions to pins_arduino.c to avoid duplicated code. Pin functions naming alignement. Move init() function to pins_arduino.c to avoid duplicated code and define it as weak. Minor clean of unused code. Remove usb flags for variants w/o usb. Serialx under switch.Disable by default Now, variant files only contain source which differ for each variants. Signed-off-by: Frederic Pillon <frederic.pillon@st.com>
